In a Victorian London ruled by the blood-drinking elite, Perry Lowell is a logical and accomplished Nighthawk: a rogue blue blood who tracks murderers and thieves for the Guild. So when she and her charming but reckless partner, Garrett, are charged with finding a missing theater starlet, it should be a simple solve.
But with an entire theater of suspects, including a flirtatious understudy and whispers of a Clockwork Menace haunting the place, tension is brewing between the pair of them. Can they come together to solve the case—or will it be too late, when the murderer turns his gaze on Perry herself?
